Function and Technology• Toothbrush works in traditional circuit• Motor
• Double Helix Groove• Moves rod connected to bottom brush up and down• Rotates rod as well to top brush to spin
• Battery• Mechanical-Power (Faraday Flashlight or linear induction)• Energy can be provided using coil-magnet system• Still recharged by traditional outlet cord
